People who would get all worked up over a covered backside which is practically engulfed in shadow and is not the vocal point of a picture, would not be people I would tend to become very close to.
Even for girls. I expect girls who are close to me at least accept those kind of photos as wallpapers. (If they can appreciate the artistic merit - even better).
